That’s certainly what these teaser shots of a prototype suggest. The design looks very much like Rolls-Royce’s existing models but with an extended roofline and a much taller ride height.

Test mules have been running around for over a year but now Rolls-Royce is transitioning to the prototype stage. The vehicles will be sent to numerous locations around the world in a challenging testing program to ensure that the end product is “effortless” in all conditions. Key among the developments will be a new all-wheel-drive system.

The idea of an off-road capable Rolls-Royce is likely still an oddity to some, but even a brand as traditional as the British maker of ultra-luxury vehicles cannot sit back and ignore the booming demand for SUVs in key markets like China, the Middle East and the United States.

As mentioned above, Project Cullinan is due in 2018. That will be a pivotal year for Rolls-Royce as it’s also when the redesigned Phantom is due. Rolls-Royce is yet to confirm which will arrive first, though it’s likely to be the Phantom as development of the flagship sedan is at a more advanced stage.
